Introduction: The objective of this experiment is to utilize the techniques of weighing and titrating to determine the total amount of MgSO4 present in an unknown sample. Standardized EDTA will be used to titrate the unknown solution. This type of reaction is a complexation reaction‚ which usually involves Lewis acids and bases. EDTA in complexation reactions serves as a chelating ligand. The base‚ EDTA‚ will bind to the metal ions‚ which serve as the Lewis acid‚ thus playing a role as a ligand

Marz Jhon V. Patricio QUANTITATIVE DETERMINATION OF THE ACIDITY OF SOFT DRINKS I. Introduction A. Principle Titration is a laboratory method that is the slow addition of one solution to another until the reaction reaches neutralization‚ which is often indicated by color change. Acid-base titration is the most frequently used procedure to determine the concentration of an acid or basic solution. This titration is also called as neutralization reaction. By adding an indicator to the solution‚ we will
